SLS utilizing distributed launch at LEO or L2

Utilize 2 SLS launches that attempt to synergize the upper stages and payloads with a distributed launch of propellant by a second SLS.

One or both SLS launches might be dual manifested with a secondary cargo or just 1 vehicle.

If 1 SLS is lofting just fuel this opens up the possibility of payloads on the second SLS, This would mean a 70 Mt in LEO which is equivalent to two (2) Vulcan ACES upper stages at 35 MT each on the first launch on a SLS and perhaps Vulcan launched refueling vehicles.
